Re: Coincidence ?
Take your conspiracy theory and do one.
All Samsung's competitors have very good reason not to make fun of the problems with the Note 7: they know how easily something similar could happen to them and how such accidents are bad for the whole sector: just as you have halo effects, you also have the manure effect. They'll be picking up more than enough extra business by doing nothing. Plus, they almost certainly rely on Samsung for some components.
